T all' whom it may Concern:

Be it known that l, JOHN ZUnvALEcz, a

citizen' of-the United States, residing at Mar-` tin, in the county 'of Fayette'and State'of Pennsylvania, have' invented# certain new and useful Improvements in Floor-Scrubbingwf'ippa-ratus, of which the followingis a specification.

This invention relates to certain new and useful improvementsfin floor scrubbing apparatus.

rlhe primary object of the invention is to provide a scrubbing machine vespecially adapted for scrubbing iioors, streets and pavements and arranged for simultaneously spreading a-cleansing-'fluid and reciprocat= ing Vdirt-dislcd'gingf means.

A furthe'rfobject of the inventionislto' provide a 1 hand-propelling scrubbing machine a adapted for spreading-fluid upon the surfacel to vbe-s'crubl'red'and for actuating reciprocating engagingV brushes ther-cover.

A still furtherlobje'ct is to l'providel a scrubbing machine having automatically reciproeating engaging brushes and also a reciprocating rubbing or pol-ishingvmember for -en-vl` gaging theworkupon the movement of the brushes in onlyfone direction.

ith these generalobject-s in view'V and' others that will app'ear'a's the nature ofthe tank-mounting frame. Fig.v 5 is a front viewl of the complete'device, certain parts being brokenV away. Fig.- `6 is an enlarged `detail sectional view taken upon the plane ofone of the vbrush-mounting means. Fig'.. '7 -is a side elevation thereof. Fig. 8 is a horizontal sectional view throughthe brush-engaging clamp, and Fig. 9 is an enlarged sectional view' throughtlie end portion of Vthe rubbing device. Y

Referring more 1n detail to the drawings,

it being' noted that'it is designedto provide a machine for completely cleaning a plain surface, an arrangement is made for spreading Huid upon the surface and violently rubbing the same. To this end, therefore, a substantially' U-sha'ped'frame 10 is prbvided'ar'- ranged horizontally and having a forward open endand further having four upright posts 11 upon which a tank 12 is positioned vfor containing" a washingor cleaning fluid such as`13, while a scrubbing brush 141 is arranged bene'atlrthe frame 10` for'reciprioL catory movement in the manner hereinafter set forth.

Thetank 12v is provided with a filling' spou'tlt') having a removable clo'surecap y16 thereon, while forwardly of the tanloutlet pipe 117 -is arranged for mounting -ah(n"izo`nY tally positioned perforated spreading pipe orhead 18, the'flo'w of fluid to the spread pipebeingcontrolled b'y means 4of a valve 19 'within theV outlet pipe`17. The brush 14 is substantiallyx-shaped having` engaging bristles20upon' the bottom the'rec'fand` n'ormallyf seatedy upon the' surface 21 Vtov be scrubbed VorE washed.- Y

A Tishap'ed: Vmountingl frame 22 is pro? videdforithe bru'shf14'having-the base piece V23' thereofy sli'dably mounted between'` the' `said rails ,of the" machine base lO'and havingits op-positeends guidingly sli'dably positioned' within Vlongitudinal slots or A ways 24 of th'e said base side rails. The main cross-pie'ce'25- of the'T-shaped frame 22 is positioned forwardly of the "ba'se 10', while mounting posts 26 for the brush'14 are provided 1 slida'bly.V mounted through" p'erfor'al tions 27 inthe'basepiece`23-and cross piece 25 'oftheframa it'b'eing understood' that all of the posts26 are intni's manner con# nectedtothefparts23 Vand* 25. The posts 26 are provided with adjustablesclamps 28- upon th'ebottoms-'thereof having opp'ositely arrangedv jaws 29 for engaging theopposite grooved edgesv 30y ofthe brush frameV 14.v

posts 26 V'and -engage'the clampsf28 for nor mally maintaining them closed upon' the'- frame14,'helical springs 32 being arranged between 'the lcollars 31 andthe frame' 22,' whereby the frame 22 is ressilient'ly.mounte'd` upon the brush 14 and the clamping' jaws 29 are resilientl'y maintained intpb'siti' VVhe'nfdesired to remove the brush 14, the

collar 31 may be elevated against the action lCollars 31 Vare freely journaled upon the of the springs 32, the jaws 29 being then released and readily disengaged from the brush 14. Y Y

Ground-engaging wheels 33 are removably mounted beneath the tank 12 being journaled upon stub axles 34 outwardly projecting at opposite points upon the side rails of the base frame 10. A gear 35 is carried by each of the wieels 33 meshing with a side pinion 36 of a gear 37 which latter gear is in constant mesh with a pinion 38 journaled upon the shaft 34 and provided with a power disk or fly-wheel 39. Pitmen 40 pivotally connect the power disks 39 with the opposite ends 41 of the frame cross piece 25. Roller casters 42 are supportingly carried beneath the rear portion of the base 10 so that the device is mounted fortraveling upon the casters and the wheels 83, the latter having suitably roughened ground-engaging peripheries. 1n operation, it will be noted that a removable handle 43 being provided at the rear of the machine attached to the tank 12, the said handle may be readily grasped in moving the device in a desired direction. During the travel of the machine upon its wheels 33, the same are turned through the described gearing imparting rotation tothe power disk 39 which by means of the pitmen 40 reciprocates the entire frame 22 and the scrubbing brush 14 resiliently mounted therebeneath. The valve 19 allows the cleansing fluid 13 from'the tank 12 to flow under pressure through the spreading head 18 directly upon the surface 21 adjacent the scrubbing brush 14 sorthat during the travel of the machine in either' direction, the brush 14 is forcibly reciprocated during the flow of the cleansing fluid upon the surface to be operated upon such movement of the said brush being incident to the travel of the machine upon its traction wheels 33.

An oblong form of cam slot 44 is provided at opposite points upon the inner surface of the side rails of the base 10 within which are mounted terminal rollers 45 of a rubbingV Y of the brush frame 22. The cam slots 44 each have a central block 48 arranged therein and having a forward inclined lower edge 49. During the operation of the brush, the connecting rod will shift the rubber 47, it being understood that the rollers 45 are initially seated in the slot extensions 52 at the forward ends 51 of the slots 54. When the rod 48 is moved rearwardly, the rollersr45 will engage the inclined forward end 49 ofV Y: the blockc48 and be directed into'the upper section of the slot 44'toride on the block 48. In this position, the rubber is completely removed from the surface 21, and a continued rearward movement will cause the rollers to Y engage the rear ends 50 of the slot and be directed into the lower section of the slot 44V with the rubber 47 in contact with the sur-v face 21.V rIhe rod-4SV at this time moves forf wai'dly and causes the rubber 47 to sweep kin a similar direction all water and dirt present in the cleaning operation of the brush 14. At the extreme forwardV position of the rubber, the rollers are received in the slot exten-`V sions 52 to'be in position again to engage Y board 46 is moved in its depressed orlowered f position during the forward movement of.:

the board and with the engaging rubber 46 upon'the `surface 21, while during the rearward movement of the rubbing b`oard,gtlie saine will be elevated and the rubber 47 will Y be at rest out of engagement with the said surface 21. The entirefmachine is forcibly j moved either forwardly or rearwardly in the' manner above described andthe surface-21 is washed by means of the spreading iuid 41V` falling thereon and the forcible reciproca tions of the brush 21 and the forward sweeping or rubbing actuations of the rubber 47 so that'by means of the machine one personY may readily perform the complete cleaning operation upon a substantially smooth surfacesuch as a pavement or floor. j

While the form of the invention herein shown and described is what is believed to be Y the preferred embodiment thereof, it Vis nevertheless to be understood that minor changes may be made without departing from the spirit and scope of the invention claimed.

What I claim as new is :4- Y A device of the class described, comprising a frame, a reciprocating brush carried thereby, the said frame including side bars having oval-shaped cam slots in their inner op'-V posite sides, a rubbing board, rollers'at Vthe ends of the said board operatively mounted within the said slots, a surface-engaging rubber carried by the said board, and a'pitman connection between the said board and y frame. Y

In testimony whereof I affix my signature.
